ERASER-HOLDER. j 1

Application filed September 14, 1912, Serial No.

RINE, a citizen of the United States,'residing in Brooklyn, in the county of-Kings and State of New York, have invented certain new and useful Improvements in; Eraser- Holders, of which the following is a specification. This invention has for its object to provide a form of eraser attachment that can be ap plied to various objects so thatthe eraser is always convenient for use, yet will not be lost. 1

The invention is especially designed for use in connection with a typewriter, to be clamped to a convenient part ofthe machine and grasped by the hand and used on the work in the machine,-and as soon as released the eraser will return to its place on the machine automatically to be always ready for future use. i I

A further object of the invention is to provide a device in the nature of a frame or casing containing winding means to wind,

up a cord that is attached by its free end to a typewriter desk or otherplace, and

which frame carries an eraser on anfextenone embodiment of my invention, Figure 1 shows the device in sideelevation; Fig. 2 is a longitudinal section; Fig. 3 shows-the outer shell of the casing; Fig. 4 is a section on the line 44 of Fig. 3; Fig. 5 is a side elevation of the device with one of the plates and the outer shellremoved; Fig. 6 is a section on the line 66 of F 3; Fig. 7 shows the sheave; Fig. 8 shows one of the frame plates; and, Fig. 9 shows the other frame.

The device, as set forth, comprises a frame' that is formed by two plates of flat sheet metal of elongated form, one plate 12 extending in a plane having the body portion 13 provided with an extension 14. At the center of the head is a stud 15 on which ro- Specification of Letters Patent.

tatesa sheave 16, shown separately in Fig.

z. This sheave is somewhat dish-shaped having a chambered portion 17 in which is placed a volute spring 18 whose inner end extends into a slot 19 in the stud 15 to lock this end of the spring, which is wound around the'studas indic'ated'in Fig. 5;, and has its outer end securedto the sheave 16,

so that when thesheave is turned to wind up the "spring, upon releasethe spring will unwind androtatej the sheave on the stud, The periphery of the sheave, is provided with a channel 20 that receives a suitable cord 21 which. is wound in this channel in the oppositedirection to the spring, so that by pulling the cord. the sheave will rotate to wind up the spring, and when the cord .is released the spring rotating the sheave will wind the cord back on its periphery.

Inn-annular shell 51 is providedhaving rib portions 22 and .23 on its. faces that are broken away at the part 24, and the inner diameter of the rib portion is such that it will receive the head13 of the plate 12, with thesheave member projecting v into the open space 25 of the shell, the headbeyond the shell enga ing the face portions 26 of the casing where it is suitably secured, An aperture. 27 is provided-in theopposit'e part of the shell froml the part 24 through which the cord-21 passes, and the edges ofthis aperture are suitably curved to prevent undue friction on thecord. A second'lplate member 28, similariin shape to platel2, is provided that has'its head portion 29 placed on the shell 51 on the opposite face from that engaged by the plate 12, as indicated in Fig. 2, and these two plates are, secured together through the shell, thereby forming 1 a casing that incloses the sheave 16 with its attached springandcord; the head 29 being provided with a circular hole forreceiving the stud 15 that is suitably secured thereto, as riveting. The extension 30 of the plate, 29 is deflected alt 81 so as to bring the part 30 into engagement with theextension 14 of the other plate, as shown in Fig. 2, and these extensions are suitably secured together, thereby forming a strong and rigid extension of the casing. These extension plates are provided with a stud 32secured at a hole 33 thereinon the inner side or' in alinement,withthesheave in the casing, and

this studgis of a size to pass throughuthe hole provided in the usual form of circular eraser'E, as shown in Figs. 1 and 2. When the eraser is placed on this stud it will be in alinement with the shell and its contents, and suitable means are provided for securing the eraser on this stud so that it can be removed and another substituted when desired. v

In the construction shown a lever 35 is hinged to the plate 28 by a pin 36, and the lever hasa slotted portion 37 that when swung will engage the slotted head 38 of the stud 32, 'and'thereby' serve to secure the eraser on the stud;'it being understood that the eraser is rotatable on the stud to present all'portions of its margins for use. Suitable means are provided for securing the .lever'in closed position, the slotted portion of the end of the lever may have a tight engagement with, the slotted head, or the lever may be provided with an extension at its inner end containing a lug 40 that, when the lever is closed onthe stud, will engage a suitable socket or depression 41 in the casing'into which it will be forced by the resilient construction of the lever.

; It will be seen that the casing with the extensionfpl'ates forms a very convenient handle or gripping means for the eraser, so that it is more conveniently presented for use than in its usual arrangement, and that as wornaway the eraser is turned to brlng all ofits edges for convenient use.

, Thefree end of the cord may be provlded with a clamp 45 having a screw 46, that can be readilyattached to'the frame of a typewriter, or to a convenient portlon of a desk.
